Emergency Medical Response You Are the Emergency Medical Responder Your ambulance unit is the first to arrive on an isolated road where an 18-year-old male driver lost control of a motor vehicle and collided with a tree. In the crash, the drivers legs were broken, and he is pinned in the wreckage. You find the driver conscious, restless and in obvious pain. After a couple of minutes, the patients condition has changed. He begins to look ill. You notice he responds only to loud verbal stimuli, is breathing fast and looks pale. His skin is cold and moist and his pulse is rapid and weak. Lesson 29: Shock
Emergency Medical Response Shock Inadequate supply of oxygenated blood to the vital organs Three conditions necessary to maintain adequate blood flow: Functioning heart Intact blood vessels with ability to constrict or dilate Adequate amount of circulating blood
Emergency Medical Response Major Types of Shock Hypovolemic Hemorrhagic is the most common type Obstructive Distributive Neurogenic/vasogenic Anaphylactic Septic Cardiogenic
Emergency Medical Response Other Types of Shock Hypoglycemic Metabolic Psychogenic Respiratory
Emergency Medical Response Shock: Early Signs and Symptoms Apprehension and anxiety Slightly lower body temperature Rapid breathing Slight increase in pulse rate Normal or slightly decreased blood pressure Pale, ashen and cool skin
Emergency Medical Response Shock: Later Signs and Symptoms Listlessness Confusion Difficulty speaking Irregular breathing Decreased blood pressure (diastolic blood pressure may reach zero) Rapid yet weak or irregular pulse Pale, cold and clammy skin Low body temperature Dilated pupils that are slow to respond to light
Emergency Medical Response Activity You are providing care to a patient who has fallen off of a 6-foot ladder into a pile of construction debris. He has numerous lacerations on his body with two large open wounds on his thighs that are bleeding profusely. The patient is pale but alert and anxious. His respiratory rate is 28 breaths per minute and his pulse rate is 104 beats per minute. His blood pressure is within his usual range.
Emergency Medical Response Shock: Care Ensure an open airway Perform a primary assessment Provide emergency oxygen and ventilatory support Control bleeding Leave patient flat in a face-up position
Emergency Medical Response Shock: Care (contd) Immobilize any suspected broken bones or dislocated or damaged joints Maintain normal body temperature Reassure the patient Do not give any food or drink Treatment for specific injuries or conditions Transport as soon as possible
Emergency Medical Response You Are the Emergency Medical Responder After extrication teams arrive, they finally free the driver from the vehicle and he is removed from the car. You notice that the patient looks worse. He now responds only to painful physical stimuli. His breathing has become very irregular. You know that the hospital is 20 minutes away.
